brake pads 11/32 at only 1300 miles

After 1349 miles the "check break pad for wear" notice came up on the dash.
Took it back to dealer, the informed me that one of the rear sensors had come lose. They put if back and problem solved.
On the service ticket there was a notation that they measured pads and it was 11/32. If that is what is left on the pads that would mean that I will only get about 2000 miles out of a set of pads.
Can someone please enlighten me on what the measurement means before I go raise hell at the dealership. Also, how likely is it that the sensor just came lose?
I am bringing the car back next week for an unrelated issue and would like to have some help before then.
Thanks
